About This Tool

Edit Markdown in the left pane and see it rendered in real time on the right. Supports headings (h1-h6), bold, italic, strikethrough, links, images, inline code, fenced code blocks with syntax hints, tables, ordered and unordered lists, blockquotes, and horizontal rules.

**What is Markdown?**

Markdown is a lightweight markup language created by John Gruber in 2004 that uses plain-text formatting syntax which can be converted to HTML. It has become the de facto standard for writing documentation, README files, blog posts, comments, and messages across platforms like GitHub, GitLab, Stack Overflow, Reddit, Discord, and many CMS platforms. Markdown is popular because it is readable even in its raw form — the formatting cues (# for headings, ** for bold, - for lists) mirror what you would naturally write in plain text.

**How the live preview works**

As you type in the editor pane, a client-side Markdown parser processes your input and renders the formatted output in the preview pane. The parsing happens on every keystroke with no noticeable delay for typical document sizes (under 50,000 characters). The rendered output includes proper typography: smart quotes, em-dashes, and curly apostrophes where applicable.

**Supported Markdown features**

The preview supports the full CommonMark specification plus GitHub Flavored Markdown (GFM) extensions: headings (# through ######), bold (**text**), italic (*text*), strikethrough (~~text~~), links ([text](url)), images (![alt](url)), inline code (`code`), fenced code blocks with language hints (```javascript), tables with alignment, ordered and unordered lists (including nested lists), blockquotes (> text), and horizontal rules (---).

**Common use cases**

Developers preview README files before pushing to GitHub. Technical writers draft documentation and see formatting in real time. Bloggers compose posts for static site generators like Hugo, Jekyll, or Eleventy that use Markdown as their content format. Students take structured notes with headings, lists, and code blocks. Content creators draft newsletters and social media posts that support Markdown.

**Copy and export**

Copy the rendered HTML output with one click to paste into a CMS rich-text editor, email template, or web page. The HTML is semantic and does not include inline styles, making it easy to integrate with your own CSS.

**Privacy**

All Markdown parsing and rendering happens entirely in your browser. No content is sent to any server.

Frequently Asked Questions
Which Markdown features are supported?
Headings, bold, italic, strikethrough, links, images, inline and fenced code blocks with syntax hints, tables with alignment, ordered and unordered lists, blockquotes, and horizontal rules. This covers the CommonMark spec plus GitHub Flavored Markdown extensions.
Can I copy the HTML output?
Yes. Click the "Copy HTML" button to copy the rendered HTML to your clipboard. The HTML is semantic and does not include inline styles.
Is any data sent to a server?
No. All Markdown parsing and rendering happens entirely in your browser. Your content is never uploaded or stored.
What is GitHub Flavored Markdown (GFM)?
GFM is an extension of standard Markdown developed by GitHub. It adds support for tables, task lists (- [x] item), strikethrough text (~~text~~), and fenced code blocks with language hints. This tool supports all GFM features.
Can I use this to draft blog posts?
Yes. Many static site generators (Hugo, Jekyll, Eleventy, Gatsby) and CMS platforms (Ghost, WordPress with plugins) accept Markdown as their content format. Write your post here, preview it, and copy the Markdown or HTML into your platform.
How fast is the live preview?
The preview updates on every keystroke with no noticeable delay for documents up to 50,000 characters. Very large documents may have a slight delay, but this is rare for typical writing tasks.
Does the preview support syntax highlighting in code blocks?
Fenced code blocks with language hints (```javascript, ```python, etc.) are rendered with appropriate CSS classes that enable syntax highlighting when combined with a highlight.js or Prism.js stylesheet.
